Red tides, aka harmful algal blooms, have been studied by scientists on the west coast of Florida. These scientists have now connected red tide events with hypoxia, low- or no-oxygen conditions. In a recent study published in the journal Harmful Algae, scientists of NOAA and the University of Miami Rosenstiel School’s Cooperative Institute for Marine and Atmospheric Studies found that when red tides began in early summer and continued into fall, hypoxic conditions are also more likely to occur. Red tide is a seasonal phenomenon. Since oxygen is vital for marine life, the combined red tide-hypoxia events can be devastating to marine ecosystems, leading to massive death of marine life.
“What we now better understand is why some red tide events are more severe than others, particularly for fish,” said Brendan Turley, lead author and assistant scientist at the University of Miami affiliated with NOAA’s Southeast Fisheries Science Center. “For example, during the event in 2005, it was estimated that about 30 percent of the red grouper population was killed.”
Scientists are also concerned that the conditions that lead to these combined events will increase with climate change projections into the future. Scientists at NOAA and many other agencies and organizations are trying to predict changing red tide conditions, so that people and businesses can plan ahead. This research is an ongoing, community-science assisted effort to monitor broad scale ecosystem changes as part of NOAA’s Integrated Ecosystem Assessment Program.

Many of you are concerned about FLORIDA RED TIDE on the gulf coast especially if you are moving to Sarasota Florida or are going to a Siesta Key Red Tide beach. Red Tide Explained: We will discuss where red tide comes from, how it affects marine life and humans, and what is currently being done about it by Mote Marine Laboratory & Aquarium. We will also head over to Siesta Key and Turtle Beach to see what red tide looks like and its effects, in the video published on Aug 8, 2021, “What is FLORIDA RED TIDE On The Gulf Coast? Siesta Key Red Tide/Red Tide Explained [2021]“, below:
Maybe you already knew that deadly algal tides discolor ocean waves, deplete the water of oxygen, and release toxins that can kill a huge range of ocean critters, but did you know that the tiny organisms that cause red tides are also an extremely important part of our ecosystem? In the video published on July 22, 2020, “The Terrifying (but Awesome) Science Behind Red Tides“, below:
You may have heard of red tides, but are you aware of their impact on people and the environment? Red tides can have a widespread effect on marine life, and can affect you if you swim in the water or consume contaminated seafood. Let’s take a look at what causes a red tide, how it impacts the environment, and what you can do to reduce your exposure to its toxins, in the video published on March 8, 2021, “What is red tide ad why is it harmful to humans and to environment?| What Science says| PH RED TV“, below:
